thank goodness for new slimful. one delicious, 90-calorie slimful and a glass of water, like before dinner, helps keep me satisfied for hours. so instead of this much, i only need this much. and slimful tastso good... i don't even miss dessert. slimful and a glass of water... eating less is a beautiful thing. jenna: well the doc is in and it's a good thing. this year's flu season already causing alarm. right now the cdc says the number of cases is spiking. at least 18 children have died so far. this has been the earliest flu season in at least a decade. it usually peak as little later this month into february. only about 37% of all of us in this country have been vaccinated which at this point we'll ask doctor siegel about that whether we should at this time. 41 states are reporting widespread outbreaks. dr. siegel is with us. should we get vaccinated if we haven't already, what is your recommendation. >> no question about it. you should get vaccinated. 15,000 reported cases. probably more like 50 to 100,000. not al
